Looking for this math tool

  • #1
I’m looking for this math tool. The purpose behind getting this will be a part of my high school trig lesson showing how I can find the height of an object using trig. I would love a large protractor like object like this but don’t even know what this one is called to search for one on amazon or eBay. Any suggestion is appreciated.

You may find the last method more appropriate to your need.
Cool! We students in Tawian needs to make a clinometer(Oh! it's called a clinometer!) when we were 10 with straws and cardboard as a part of our lesson of observing the moon:wink:(part of my old textbook)
